The dried and fired brick specimens were characterized following
the technical rules. In particular, water absorption (24-h immersion),
weight loss% and rupture modulus (MOR) (follows EN 100 and
ISO 10545-4) by a flexometer (Gabrielli mod. CR4/CR5-E5, Italy)
were determined in the laboratory fired samples in comparison to
the standard one. From experimental practice, laboratory samples
with a MOR below 200 kg/cm2 are not suitable if transferred to an
industrial scale and extrusion molding
